Ethereum for the 4th grade

Once upon a time...

In a world where magic is reality, a group of daring adventurers gathered around an ancient table in a strange house. On the table lay an unwritten magic book, known as "The Book of Eternity". This book had the power to change reality for those who knew how to write tales in its pages. Tales that could contain magical formulas.

The game began when they placed their gold coins on the table, which were locked by the book's magic and turned into tickets with unique numbers (like lottery tickets). The more gold coins, the more tickets. Additionally, players received a number of extra tickets related to the time they had been playing. Thus, the longer you play, the more extra tickets you receive. The objective of this game is to fill the magic book with tales, with each tale being written on a new page of the book. In each round of the game, a new page of the book is created, and players propose their tales in order to write the tale on the new page and realize their wishes. Every tale must adhere to certain rules. The main rule is that to create the tale, players must choose different descriptions from a large basket of descriptions.

Now, the owner of the house, who has the lottery machine, draws a ticket randomly in each round of the game. Under these conditions, it's clear that the player with the most tickets will have a higher chance of being chosen. So, it will be the player who is chosen by this lottery who gets to write the tale on the new page.

Once the tale is chosen and written on the page, someone must check that it follows the rules. The owner of the house randomly selects some of the players to form a verification committee, which is newly created in each round of the game. The members of the committee check, each independently, if the tale adheres to the rules. If the majority of the members, (for example, at least two-thirds) confirm that the tale is in order, then the new page is added to the book. When the new page is added to the book, the magic book is activated, and if the tale contains spells, it cast these spells in the book's magical world.

To motivate people to participate in the game, once the round is closed, the player who proposed the new tale wins a quantity of coins, as do the committee members who did the verification. For committee members who cheat, for example by verifying tales that are not in order, there are penalties. One of the ways of punishment is taking away a quantity from their coins. There... I just told you what Ethereum is.
